2. The method of claim 1 , further comprising: forming a logical link control and adaptation protocol (L2CAP) connection with the target device, wherein the specific channel is an L2CAP channel.

3. The method of claim 1 , wherein the specific channel is selected based on at least one of interference of the mesh network, latency necessary for the firmware data, or reliability.

4. The method of claim 1 , further comprising: fragmenting the firmware data into a plurality of data based on a data size supported by the specific channel, wherein each the plurality of fragmented data comprises an identifier indicating that the fragmented data corresponds to specific fragmented data of the firmware data, and wherein the state information further comprises a product identifier identifying the target device.

5. A method of for transmitting and receiving data for providing, by a first manager device, a specific service in a mesh network of a wireless communication system, the method comprising: receiving, from a target device, state information related to an update of firmware for providing a specific service; transmitting, to the target device, a request message to request the update of the firmware of the target device based on the state information; selecting a specific channel among a plurality of channels for a transmission of firmware data, wherein the plurality of channels are configured to transmit and receive data of at least a specific size; transmitting the firmware data through the specific channel; and receiving, from the target device, a message indicating completion of the firmware update, wherein the state information comprises a version identifier indicative of a current version of the firmware, receiving an advertising packet from the target device and each of a plurality of adjacent target devices in order to provide the specific service, wherein each of the advertising packets comprises environment information measured by a corresponding one of the plurality of adjacent target devices and the target device and location information for estimating a location of the target device; calculating a distance value indicative of a distance from the first manager device to the target device or the plurality of adjacent target devices based on the location information; calculating a control value for the locations of the target device or each of the plurality of target devices on which a specific operation is to be performed based on the environment information and the calculated distance value; and performing the specific operation based on the calculated control value.

6. The method of claim 5 , wherein the control value is calculated by of multiplying the distance value and a specific scale factor.

7. A first manager device for providing a specific service in a mesh network of a wireless communication system, the first manager device comprising: a transceiver; and a processor functionally connected to the transceiver, wherein the processor is configured to: receive, from a target device, state information related to a firmware update for providing a specific service; transmit, to the target device, a request message to request the firmware update of the target device based on the state information; select a specific channel among a plurality of channels for a transmission of firmware data, wherein the plurality of channels are configured to transmit and receive data of at least a specific size; transmit the firmware data through the specific channel; and receive, from the target device, a message indicating completion of the firmware update, wherein the state information comprises a version identifier indicative of a current version of the firmware, receive, from the target device, an advertising packet in order to provide the specific service, wherein the advertising packet comprises environment information measured by the target device and location information for estimating a location of the target device; estimate the location or direction of the target device based on the location information; perform a specific operation for providing the specific service based on the estimated location, receive, from a second manager device, a negotiation request message for determining a manager device for performing the specific operation, wherein the negotiation request message comprises a first general parameter and first specific parameter for determining the manager device; determine the manager device among the first manager device and the second manager device based on the first general parameter, the first specific parameter, a second general parameter, and a second specific parameter; and transmit, to the second manager device, a negotiation response message comprising determination information indicative of the determined manager device, wherein the specific operation is performed by the determined manager device.
